[libvirt] [PATCH v4 00/17] LXC IP configuration feature
by Cédric Bosdonnat
Hi all,
Here is an updated version of the lxc IP configuration patch series.
Diffs to v3:
* Took care of Daniel's feedback
* Fixed openvz driver to add support for multiple --ipadd
* Report an error for drivers using IP addresses, but only the first one
in case there are more provided.
* Squashed Patch 11 to have virDomainNetIpsFormat right in the first place
* Fixed regression introduced in qemuConnectDomainXMLToNative: IPs were not
kept over memset for bridge type.
* Reformatted to fit latest make syntax-check changes
Cédric Bosdonnat (17):
Forgot to cleanup ifname_guest* in domain network def parsing
Domain conf: allow more than one IP address for net devices
LXC: set IP addresses to veth devices in the container
lxc conf2xml: convert IP addresses
Allow network capabilities hostdev to configure IP addresses
lxc conf2xml: convert ip addresses for hostdev NICs
Domain network devices can now have a <gateway> element
lxc conf2xml: convert lxc.network.ipv[46].gateway
LXC: use the new net devices gateway definition
LXC: honour network devices link state
virNetDevSetIPv4Address: libnl implementation
Renamed virNetDevSetIPv4Address to virNetDevSetIPAddress
virNetDevAddRoute: implementation using netlink
virNetDevClearIPv4Address: netlink implementation
Renamed virNetDevClearIPv4Address to virNetDevClearIPAddress
Openvz --ipadd can be provided multiple times
Report error if a driver can't handle multiple IP addresses

[libvirt] [PATCH] CVE-2014-8131: Fix possible deadlock and segfault in qemuConnectGetAllDomainStats()
by Martin Kletzander
When user doesn't have read access on one of the domains he requested,
the for loop could exit abruptly or continue and override pointer which
pointed to locked object.
This patch fixed two issues at once. One is that domflags might have
had QEMU_DOMAIN_STATS_HAVE_JOB even when there was no job started (this
is fixed by doing domflags |= QEMU_DOMAIN_STATS_HAVE_JOB only when the
job was acquired and cleaning domflags on every start of the loop.
Second one is that the domain is kept locked when
virConnectGetAllDomainStatsCheckACL() fails and continues the loop when
it didn't end. Adding a simple virObjectUnlock() and clearing the
pointer ought to do.
Signed-off-by: Martin Kletzander <mkletzan(a)redhat.com>
---
Since this is very low priority and it was mistakenly disclosed in
another patch there is no embargo on this CVE. Patches to maint
branches will be pushed after back-porting (couple of minutes).
Having said that, I am probably not the right one to write up the
libvirt security notice, but I'll try drafting one, eventually.

[libvirt] [PATCH] qemu: bulk stats: typo in monitor handling
by Francesco Romani
A typo in qemuConnectGetAllDomainStats makes the code
mark the monitor as available when qemuDomainObjBeginJob
fails, instead of when it succeeds, as the correct flow
requires.
This patch fixes the check and updates the code documentation
accordingly.

Hi, libvirt list,
I'm not sure if Cole's suggestion could be done in libvirt, so just forward
the mail to libvirt mailing list. Any opinions?

[libvirt] [PATCH] storage: unify permission formatting
by Martin Kletzander
Volume and pool formatting functions took different approaches to
unspecified uids/gids. When unknown, it is always parsed as -1, but one
of the functions formatted it as unsigned int (wrong) and one as
int (better). Due to that, our two of our XML files from tests cannot
be parsed on 32-bit machines.
RNG schema needs to be modified as well, but because both
storagepool.rng and storagevol.rng need same schema for permission
element, save some space by moving it to storagecommon.rng.

[libvirt] [PATCHv4 2/2] security: Add a new func use stat to get process DAC label
by Luyao Huang
When use qemuProcessAttach to attach a qemu process, cannot
get a right DAC label. Add a new func to get process label
via stat func. Do not remove virDomainDefGetSecurityLabelDef
before try to use stat to get process DAC label, because
There are some other func call virSecurityDACGetProcessLabel.
Signed-off-by: Luyao Huang <lhuang(a)redhat.com>

v2 add support freeBSD.
v3 use snprintf instead of VirAsprintf and move the error
settings in virSecurityDACGetProcessLabelInternal.
v4 remove errno.h include and thanks Eric advice move this
version comment to this place.

in Fedora 20.
First enabling hugepages causes a machine to refuse to boot. It gives
errors saying "Error starting domain: Unable to read from monitor:
Connection reset by peer "
This problem is easily reproducible, all you have to do is add the
setting to any vm you have.
Second is the vm does not work if a shared folder is added. I only tried
adding them as mapped mode.
Please try to fix them.
